摘　　要：本文介绍了新型的生物滤池──变速厌氧生物滤池，选用核桃壳、炉渣、陶粒三种填料进行了挂膜特性试验。结果表明，粒径２．０～５．０ｍｍ的炉渣挂膜性能较优。变速厌氧生物滤池的开发，在降低滤池出水ＳＳ值和防止滤池堵塞这两个方面取得了进展。A new type biofilter-variable-velocity-anaerobic biofilter is introduced in this paper.The walnut shell, cinder and ceramsite are chosen for experiment on forming biofilm. The results show that the cinder with diameter 2.0-5.0mm has good performance in forming biofilm. The development of varable-velocity anaerobic biofilter has made progress in decreasing effluent SS and preventing jam in biofilter.
